Research of a Dynamic Parallel I/O Scheduling Algorithm Deng Hui-min1, ZENG Bi-qing2* 1 (Department of Computer Engineering, HuNan Institute of Technology, HengYang HuNan 421008) 2 (Department of Computer Engineering, NanHai Campus, South China Normal University, NanHai Guangdong 528225) Abstract: Parallel I/O is an important way to improve the performance of the distributing computer. Based on the research situation of the parallel I/O data scheduling policies, a new data scheduling policy named the dynamic I/O scheduling algorithm of two times scheduling and self-maintenance load balancing(DIO_TSMB) is proposed. The experimental result has shown the validity. At last, the future development of parallel I/O data scheduling is presented.
